[otrs] Mysql 4

Hello, I´m trying to figure out how to update MySQL 3 to 4. Unfortunately, I don´t know how to solve the dependencies as I don´t know if OTRS relies on these packages. Do I have to specify multiple rpms for a simultaneous update? [root@--- root]# rpm -U MySQL-server-4.0.15-0.i386.rpm warning: MySQL-server-4.0.15-0.i386.rpm: V3 DSA signature: NOKEY, key ID 5072e1f5 error: Failed dependencies: libmysqlclient.so.10 is needed by (installed) perl-DBD-MySQL-2.1017-3 libmysqlclient.so.10 is needed by (installed) php-mysql-4.2.2-8.0.8 [root@--- root]# Cheers, Lars
